ABSTRACT

A quadrat-based survey was undertaken on the flora and floristic communities of several ironstone ranges and outcrops in the Yalgoo bioregion, covering the central extent of the Tallering Land System. One hundred and three 20 x 20 m quadrats were established over the extent of this region, and covered the topographic profile of these landforms. A total of 414 taxa (species, subspecies, varieties and forms) and four hybrids were identified from these quadrats. Fifteen taxa of conservation significance were found in this survey, five of which had not been previously recorded from the area. Significant range extensions for 21 species are reported in this study. At least nine new taxa were identified, of which several are of conservation significance. Nine regional endemic and near-endemic taxa were found over the study area, with half restricted to the south-west hills. Eight floristic community types (five main types, two with subtypes) were resolved from classification analysis of floristic data (presence / absence). These community types were strongly associated with topography and soil chemistry. Geographical variation was found among the floristic communities within the region, and some communities were found to be restricted to the south-west of the survey area. These restricted communities were found to occur in the more mesic regions of the survey area, on rocky uplands of BIF, and had notable component of flora from the South West Floristic Region. The central Tallering Land System is currently unreserved, although three pastoral leases have been purchased by the Western Australian Department of Conservation and Land Management (CALM) (now known as the Department of Environment and Conservation (DEC)) with the intention for future inclusion in the conservation estate. Mining and exploration tenements cover nearly all of the central Tallering Land System. This area has significant conservation values, and proposed mining activities must be assessed and managed to minimise impacts on significant flora and floristic communities.

Land Use History (CALM 2004). The current tenure status of this area is Unallocated Crown Land, and is in the process of tenure The lands within the Yalgoo bioregion have been subject review with the intention of this area becoming to pastoral and mining activity, although it has not been conservation estate. These former leases have been subject to extensive land clearing like the adjacent subsequently de-stocked, wells closed and feral animal wheatbelt region. Pastoral leases were first established in eradication programs implemented (CALM 2005). the study area in the latter half of the 19th century, Gold discoveries in the late 19th century led to the commencing with Thundelarra (Pinyalling Spring) and establishment of towns and gold mining activities in the Badja stations in the early 1870’s, and with most leases region (Beard 1976a; Hennig 1998a).

Five main community types were recognised, with three Environment and Conservation, Western Australian Herbarium, Kensington of these communities (1, 4 and 5) further divided into Flora and vegetation of Tallering 129

The primary division separates floristic communities on lower slopes, footslopes, colluvial outwashes and plains (type 5) from those on hillslopes, crests and upland plateaux (types 1, 2, 3 and 4). Hence, the first major distinction was between the lowland tall open Acacia shrublands and Eucalyptus woodlands from the shrublands and thickets on the hillslopes and uplands. This division is also discernable on the sorted two-way table ordered by the site and species classification (Appendix 2), and is particularly evident in Species groups G, J and L. Below this primary level of divergence, four floristic communities were identified for the crests, slopes and foothills on the ironstones of the Tallering Land System. The second major division separated Community types 1 and 2 from Community types 3 and 4, which coincides with the segregation of the southern and western sites with richer loamy soils from the eastern and northern sites in drier situations (outcrops) and on more skeletal soils. This division is associated with Species Group H, and, to a lesser extent, group G (Appendix 2). Community type 1 was a relatively wide-ranging community found from Mt Karara to the northern and eastern limits of the study area. It consists of both the lower slope Acacia shrublands with emergent Eucalyptus woodlands and upper hillslope and crest shrublands. This community is subdivided according to floristic differences associated with topographical position. Community type 1a occurs on ironstone substrates that were low in the landscape (at an average altitude of 361 m), either on the lower slopes of hills, small massive outcrops of banded ironstone formation or low rises in the upland peneplains. It is distributed from Mt Karara to the strikes of BIF north of Minjar Hill and east to the footslopes of Warriedar Hill, but was absent from the extreme south-east extent of the study area. Community type 1a is differentiated from Community type 1b by being relatively species poor (Appendix 2), and lacking good representation of the ubiquitous Species Group G. The majority of species from Species Groups H and I are well represented. There is an average of 38.9 ± 2.6 total taxa Figure 2.

Therefore, the floristic understorey species for both this community, and communities have been resolved at two levels, these being Community types 1b and 2.

Even within this community there goldfields (Gibson et al. 2007). Within the wider region were differences in particular species and species groups of the northern Yilgarn, the central Tallering Land System, between Mt Karara and Windaning Hill (e.g. Persoonia especially the Mt Karara – Windaning area, is comparatively hexagona was only located on Mt Karara, whilst Acacia rich in endemic and near endemic taxa. woodmaniorum was not located on Mt Karara). Such Trends in endemism and species diversity on BIF ranges geographical variation (east – west) within this community across the Central Tallering land system are on a small type has been confirmed by subsequent surveys (Woodman scale relative to the wider region, but mirror those Environmental Consulting Pty Ltd 2007). documented for other BIF ranges and granite outcrops in The findings of this study reiterate those from other the Yilgarn Craton, and in the overall southern Western studies (e.g. Gibson 2004 a, b; Gibson & Lyons 1998, Australian flora (Beard 1976a, 1990; Gibson et al. 2007; Markey & Dillon 2008), that there are differences in Hopper et al. 1997; Hopper & Gioia 2004).

The limited dispersal between ranges, stochastic events of tendency for lower slope outwash sites to have relatively immigration or local extinction, in situ speciation events, less acidic soils probably relates to the higher and range-specific habitats and substrates to account for concentrations of cations and higher eCEC, which buffers biogeographic patterns currently observed in BIF ranges against acidity (Gray & Murphy 2002), whilst skeletal soils of southern Western Australia (Hopper et al. 1997, are being derived directly from heavily weathered rocks. Hopper & Goia 2004). Like granite outcrops (Hopper et Other studies have reported more basic soils (pH > 8.0) al. 1997), BIF ranges in the northern Yilgarn are in outwash locations which have been derived from the biodiversity hotspots, and refugia for endemic or weathering of mafic rocks and calcretes. In turn, these uncommon taxa and floristic communities (Gibson et al. sites support quite distinct vegetation communities (e.g. 2007). Gibson & Lyons 1998, 2001b).

Table 1 Taxa of conservation significance collected within the Central Tallering Land System. Priority conservation status is according to Atkins (2006), and population status refers to whether the population was unknown or known prior to this study. Endemic taxa are defined as those restricted to hills within 100 km radius. IBRA Regions are denoted as: Yal = Yalgoo, Mur = Murchison, AW = , GS = Geraldton Sandplain (Thackway & Cresswell 1995, Environment Australia 2000). Asterisks indicate that the distribution is centred on Yalgoo IBRA.
